Not sure if this is already a thing (and it probably would have a very small audience/users), but it would be helpful if I could manually ‘delay’ certain DNS lookups in order to slow down the connection to certain websites. Would be particularly helpful to nudge people off Google on my network. I’m sure it would have more serious applications as well, haha.
If there is some way to do get similar results using the router of the network, please let me know as well.
My opinion - this is well outside the scope of what Pi-hole does or should do. You want to use Pi-hole to attempt to control user behavior on your network.
